I wouldn't say thickness, but proportions
Since you brought up this example: I have this Urushi dial Seiko chronograph, and basically I like it. Its thickness is not so much of an issue. However, its design makes it an elegant timepiece, and for that design goal, it is kinda thick.
Much more disturbing for me are wrong proportions that make a watch unattractive. To stay with the Seiko example: The iconic Marinemaster is shown in almost all official photographs from plainly above, so you do not really see its massive thickness. For a diving watch, a high-building case is not a problem. IN my eyes, it does become a problem if it does not match the rest of its design features. So the Marinemaster has a very small dial , compared to its chunky case, its bracelet/strap is not wide enough to optically match the massive case either. Add to this a very conventional pressure rating (its case would suggest at least 500 to 1,000 meters instead of 300), this does annoy me, especially after I realize all this when holding the real piece in my hands.
